The following editor will bring you a brief discussion on the usage scenarios of scipy.misc.logsumexp function in python. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let's follow the editor and take a look. The input parameters of the scipy.misc.logsumexp function are (a, axis=None, b=None, keepdims=False, return_sign=False). The specific configuration can be found here. The returned value is np. log(np.sum(np.exp(a))). What needs to be emphasized here is the scenario in which this function is used: Generally speaking, this function is mainly used for operations with very small values (such as Monte Carlo sampling samples). In this case, keeping the data in log processing is a must. So at this time, if you want to accumulate and sum the data in the array, you need to calculate log(sum(exp(a))) like this, but doing so will cause some accuracy problems, and this problem scipy.misc.logsumexp is The solution has been introduced, so you can directly use scipy
